How do I know if grub worms are killing my lawn?

The first thing I noticed was my grass wilting and turning brown in patches. It would then start to die, and when I would remove the patches of dead I would find the worms underneath the plant eating the roots. I also had an increased presence of birds in the yard, feeding on the grubs I assume.

Grubs cause damage to the roots of your lawn. When this occurs you will start to see brown patches in the lawn. Pulling on the lawn in these patches, you will find the roots are no longer rooted into the topsoil and pull out easily. Resoding is needed to repair.

Damage from grubs is most notable from late summer to early fall. They leave irregular brown patches throughout the lawn. These patches should peel away from the soil like a piece of carpet. Dig up small sections of your lawn, couple inches deep, around these areas and look for them. They are about the size of a nickel.
